Question

将web2py中的应用程序从python 2迁移到python 3并在本地主机中对其进行测试后，我尝试更改正在使用的服务器的配置，以使其能够与python 3一起使用。

在使服务器正常工作的许多尝试之后，我意识到我一直遇到相同的错误。 apache错误日志显示，当wsgi应该是字节字符串时，wsgi无法读取字符串，在我看来，这似乎是其中一部分配置仍在尝试使用Python 2处理该应用程序。在不重新安装整个组件的情况下，我可以采取哪些步骤将Apache的配置文件完全转换为python3？

以下是我尝试过的事情的详细信息：

-使用update-alternatives更改默认的python版本

-使用virtualEnv专门与python 3一起运行应用程序

-使用不同的方法重新安装mod_wsgi，以指定要使用python3并确保在之后启用它

-重写启用了mods的文件夹中的.load和.conf文件。

-更新web2py版本

我的想法不多了，非常感谢您的帮助。当前，这是重新安装mod_wsgi（并可能在此过程中搞砸了）之后apache2中的错误日志：

启用了mods / wsgi.conf：

WSGIScriptAlias / /home/www-data/web2py/wsgihandler.py

启用了mods / wsgi.load：

LoadModule wsgi_module modules/mod_wsgi.so
